This stat takes all your successes & dtracts from all your epic fails & Bruno is a perfect example of this.. His overall KO% is nowhere near Vitali"s so that's where it ends for him. Hide had a similar ratio before Vitali laid waste to that.. glass jawed British sluggers are a dime a dozen... HARRISON.. bRUNO hIDE.. haye Lewis... etc..etc... any more questions... son?

Vitali Klitschko had over 90 % for most of the time but now its below 90 cause some guys went the distance.
David Haye has almost 90 %.
William Fernando Souza Bezerra: 97 % KO ratio
James Kirkland and Golovkin and Matthysse are high but not 90 %
